I like Nithin Kamath, the founder of Zerodha, one of India’s cheapest lowest brokerage firm. I have watched/listened to few of his interviews on TV, Radio and his journey is impressive!
I am a customer of Zerodha and like the platform (though there are many improvements possible).
Here is a detailed chat with Nithin Kamath where he explains the success story of Zerodha. This is one company to watch out for in next few years, as they diversify into other aspects of Financial Services.
One word of caution: The interviewer is really pathetic. He is not equipped to have such discussion. Really mediocre.
